When buying a replacement laptop
DC jack, the connection to the power adapter and motherboard must be matched.
A visual comparison of your broken or loose jack to what we have pictured can rule out any obvious differences.
The color may vary. but the diameter of the center pin and external barrel should match the size of your
old jack and power adapter tip for the proper fit and a secure connection.
The pins or wires connecting to the motherboard will need to be the same as well.
Machina Electronics has
identified the correct DC power jack used by thousands of laptop models.

For notebook
DC jacks not attached by a wire cable, they will need to be soldered onto the board and the leg pins or "feet"
need to have the same configuration. For power jacks that require soldering we recommend the installation
be completed by someone with experience to ensure a reliable repair. Nearly all of the
power jacks we stock are OEM power jacks and are manufactured by the same factory that made your original
jack. These component manufacturers include Foxconn, Singatron, and Suyin.
Machina Electronics strives
to supply the best DC jacks that are an exact match for your model, and uses our direct exeperience
opening and parting out laptops to surpass the competiton in knowledge and avoid costly mismatches.
